I To all whom t may concern:

Be it known that I, JOSEPH DARGo,`a citizen of the United States, residing at New` York, in the county of New York and State 0f New York, have invented new and'useful Improvements in Window-Screens, of which the following is a specification.

This inventionrelates to window screens, the invention being more particularly related to adjustable window screens` of the wire netting type. v

A principal object of the invention is the provision of a window screen, of the wirev netting type, which is adapted to be rolled up .like a shadeand which may be adjusted laterallyf in order4 to be employed :in win-4 dows differing in Width.

Another object of this invention vis the provision of a 'device of this character combined with means to enablel ready attachj ment to any window of ordinary width, and

also to enable ready removal when desired.

With the foregoing and other' objects, which will become more apparent as the description proceeds, the invention resides in the novel constructions, arrangement andv combination of parts hereinafterl described and shown' in the accompanying drawings, forming a part of this specification, and in which Figure 1 is a view in front elevation of the invention, `showing it applied to a window. l v

Fig. 2 is a sectional view taken on the line 2 2 of Fig. l.

Fig. 3 is a detail viewk in perspective of the device,`parts being in section and parts being broken away.

Fig. 4 is a sectional view taken on the line 4 4 of Fig. 3.

Fig. 5 is a similar View taken on the line 5 5 of Fig. 3. l

Fig. 6 is a similar view taken on the line 6 6 of Fig. a

Fig. 7 is a similar view taken yon the line 7 7 of Fig. 8.

Fig. 8 is a fragmental detail view, illus-y trating the guides employed for holding the netting.

Referring more particularly to the accom. panying drawings, I illustrate in Fig. 1, a window frame typical of the kind usually employed in dwellings, ofli'ce buildings and the like, and comprising the -usual side frame parts 10 and 11, and the top and bottom frame parts 12 and 13.

As a means of supporting the elements to be hereafter described, I secure a bracket as 14 by screws as 15, or other suitable means, adjacent the top ends of the confronting sides ofthe parts 10 and 11. Each of these brackets 14'is'formed on its inner side -with longitudinal confronting flanges as 16, the saidflanges traversing the verti' cal plane which lie the parts 10 and 11;

Supported by each of the brackets l4and slidable horizontally in the opposed grooves formed by the flanges 16 thereof, is a bracket as 17 having a projecting head 18 whichzjis provided with an opening 19 suitable for'ythe reception of the iattened end of the axis element of the roller to be later described.- It will be noted in this connectionthat the brackets 14 are to be secured I to the inner confronting surfaces of the parts'lO and 11 in such manner that the openings 19 are in horizontal alinement.

For the revoluble support, upon the brackets 17, of the screen or wire netting elements, .I provide a roller, which in order to be adjustableA lengthwise, is comprised of tw`o` parts 20 and 22, respectively, whose inner ends 21 and 23 vare of reduced diameter, one of the reduced ends 23, being considerably longer than the other. Upon the shorter reduced'end 21, I secure by screws as 24, a coupling or sleeve 25 for thel reception of the longer reduced end 23. In this mannen I provide for ythe longitudinal adprovided with a central longitudinal cavity as 26 for the suitable reception of Va pin or aXis as 27 together with its encircling coil spring 28, by which it is attached at 29 to bearing 30,v ixedly secured to the annular flange of a cup member 31, carried by the roller, the said azgis terminating in a flattened endwhich engages the opening 19 in the bracket 17. l

i Upon the axis 27, and secured to the outer face of the bearing 30, is a ratchet 32, the periphery of which is formed for engagement with the pair of pawls 33, also pivoted to the outer face of 30, whereby to prevent backward motion of the roller. The mechanism here described for rotatably supporting `the roller is typical of that employed for well-known window shade rollers, and it will be understood that the roller 20 is provided with identical elements and operatively mounted in all respects like 22. 4 f

Windable upon the roller sections are the screens or wire netting sections 36 and 37 with the end of 36 overlapping the end of 37 as best shown in Fig. l.

A projection 38, slidable in the recess 34, provided in both sections 2O and 22 in alinement and also in a suitable corresponding slot in the sleeve 25 is employed to fasten the inner end of the screen section 37 to the rollers.

By means of this arrangement it will be seen that the reduced diameters of the roller sections 2O and 22 provide an annular channel for the reception of the overlapped portions of the netting sections, and that this in turn permits the convenient employment the lower window sash as desired, by means of a hook as 42 adapted to engage in an eye screw as 43.

ln order to protect the operating mechanism from the elements as well as to conceal it from view, I provide a casing 44, made in two sections, the inner end of one overlapping the inner end of the other so as to be adjustable lengthwise, relatively to compensate for windows of vdifferent width, a

connecting rod having opposed slotted 'heads 46 operable upon screws 47, or other suitable means, serves to adjustably connect the sections. After suitable adjustment, the

casing is secured by screws, or any suitable neans to convenient frame parts of the win- From the foregoing description, taken in connection with the accompanying drawings, the operation of my adjustable window screen will be obvious.' rlhe roller sections 20 and 22 as well as the netting sections 36 and 37, are adjusted relatively with respect to each other to iit the width of the window to which they are to be applied; whereupon the brackets as 17, engaging the fiat terminals of the roller axis, are applied to the brackets 14. Casing 44 is then applied, concealing the device from view, and protecting it from the elements. Arranged in this manner, the screen is adjustable so as to meet the widths of various windows; and when applied to the window, may be elevated and lowered like a window shade to suit'the convenience of the person employing it. i

Having thus described my invention, what l claim iszl In a window screen construction and in combination, two roller sections formed with equal outer end portions and each having an inner end portion of reduced diameter, the4 said reduced end of one being shorter than the other, means on the shorter reduced end for telescoping the longer one, two wire netting sections adjustably clamped on the connected rollers and adapted to be Wound and unwound thereupon accordingly as the said rollers are rotated, the said netting sections having their inner longitudinal ends overlapped and the said overlapping portions following the annular channel formed by the reduced diameter portions during the rotative actions.

ln testimony whereof I have signed my name to this specification.
